摘要:
通过对非制冷红外探测器用AIN多层大腔体陶瓷布线基板的结构设计、成型及平整度的分析研究发现:当腔体倒角达到R=0.5m叫能够实现大腔体倒角不开裂;通过改进等静压橡胶模具,解决了大腔体制作过程的分层鼓泡,实现AIN多层大腔体生坯的制作;通过优化等静压曲线及烧结整平模具设计,解决了大腔体平整度问题,达到客户提出的平整度要求,最终产品通过验证,成功开发出非制冷红外探测器用AIN多层陶瓷工艺。

摘要:
基于三族氮化物(III-nitride)材料的紫外发光二极管(UV LED)在杀菌消毒、聚合物固化、生化探测、非视距通讯及特种照明等领域有着广阔的应用前景,近年来受到越来越多的关注和重视.在过去的十多年里,氮化物UV LED取得了长足的进步,发光波长400–210 nm之间的氮化物UV LED先后被研发出来,短于360 nm的深紫外LED(DUV LED)的外量子效率(EQE)最好结果已超过10%,很大程度上得益于核心Al Ga N材料制备技术的进展.通过提高Al Ga N外延材料及量子结构中的Al组分,可以实现更短波长的UV LED,但是源于Al(Ga)N材料的特性,随着Al组分的提高,高质量材料外延和实现有效掺杂面临越来越高的挑战.本文首先从材料外延和掺杂研究的角度出发,分别从UV LED的量子结构与效率、关键芯片工艺、光提取、可靠性与热管理等方面,详细阐述探讨了发光波长短于360 nm的DUV LED研究中面临的核心难点及近年来的一系列重要研究进展.

摘要:
The Hashemite Kingdom of Jordan has a large reserve of raw Bentonite in the area of Ain Al-Baida at Basin of Al-Azraq city that has not activated yet to become valid as drilling mud. The Ore Ain AL-Baida Bentonite was investigated and activated by Na2CO3. The products were investigated by chemical analysis, X-Ray Diffraction, rheological properties and free swelling index with clay fraction. It was observed that the activities clay ranged between 0.98 < AC < 1.48 medium to high content of clay minerals. In addition, it was determined the Atterberg limits, the results of plasticity chart and relation between index and clay fraction. This means that the amount of the attracted water will be suitable influenced by the clay that is present in Ore Ain Al-Baida bentonite. The liquid limit was ranged between 83% to 140%, and plastic limit ranged between 39% - 48%. Also, rheological properties (apparent viscosity, plastic viscosity), gel strength, yield point, filtrate loss. These properties have been compared with those standard specifications properties required for the drilling fluid in order to know the appropriate circumstances to activate the Bentonite ore of Ain Al Baida at Azraq basin to become close to the standard specifications required for the drilling fluids, the ratio between Y.P/P.V was ranged 0.88 to 1.21, it is meant that the behavior of drilling fluids confirms the Bingham plastic and power-law rheological models using fine grinding of bentonite mixture with 3% - 6% concentration of sodium carbonate powder.

摘要:
Concerning this big SBEI (West of Morocco), its bioecological qualities especially its very specific and original flora has attracted naturalists for a long time. This region seems to be relatively preserved still despite the erosion and anthropogenic advanced threats. The most effective method to evaluate the degree of environmental’s change caused by anthropogenic activity and climatic conditions is the multi-date study of land cover. For this, the purpose of this work is to analyze the land cover’s changes evolution in this SBEI from remote sensing technics. Concerning that, we did a triachronical approach on data from 1988 to 2000 and from 2000 to 2010 (LANDSAT imagery). The land cover’s maps that we got were produced from a supervised classification. The analysis of time series of LANDSAT images has shown that, during the period 1988-2000, the forests area decreased to the benefit of cultural practices (period before the creation of the SBEI), while the shrub strata distribution area has clearly increased during the period 2000-2010.

摘要:
铝渣灰中的氮以AIN形式存在并与其它成分紧密混杂.进行了AIN水解、回收液氨及硫酸铵的试验研究.A1N水解产生的氨经精馏、压缩、冷凝可获得成品液氨,或者经工业硫酸吸收、结晶、离心烘干得到铵盐,氨氮回收率达95%.%Ammonia exists in form of nitrogen in aluminum slag ash and is closely mixed with other components. The tests of AIN hydrolysis and the recovery of liquid nitrogen and ammonia sulfate were conducted. From the ammonia produced in the hydrolysis of AIN, Liquid ammonia could be obtained by distillation, compression and condensation, while ammonia salt could be obtained by industrial sulphuric acid absorption, crystallization and centrifugal drying, the recovery of ammonia nitrogen could reach to 95%.

摘要:
采用密度泛函理论(density functional theory)和Gaussian03程序包研究AIN MOCVD (metal organic chemical vapor deposition)的生长模式,得到与实验观察相一致的计算结果,给出AIN MOCVD在衬底上生长出单层薄膜后,然后进行的是岛状生长而不是层状生长的理论解释.%DFT (density functional theory) and Gaussian03 software package were adopted to investigate the A1N MOCVD (metal organic chemical vapor deposition) growth mode. The computational results were good in agreement with the experimental observation. The theoretical explanation, that the monolayer film of AIN MOCVD fistly developed on the underlay, then the island growth not layer growth occured, was given.
